Description

[0001] METHOD AND ELECTRONIC DEVICE FOR PROVIDING HAPTIC FEEDBACK [0002]

The embodiments disclosed herein relate to a method for providing haptic feedback in response to a user's touch and an electronic device for performing the same.

Electronic devices such as smart phones, tablet PCs, smart watches and the like can execute various applications in response to a user's touch. The electronic device may provide appropriate haptic feedback (e.g., vibration) in response to a user's touch. Through haptic feedback, the user can clearly see that the touch has been done correctly and clearly recognize that the corresponding action is being performed.

In providing haptic feedback, an application processor may control the operation of a touch controller and a haptic controller. When a user's touch is input, the application processor operates in an awake mode and can control the haptic controller to provide haptic feedback. When a user's repeated touch is input during operation in a sleep mode to reduce power consumption, the application processor can not operate in the sleep mode and can continue to operate in the awake mode. As a result, the repetitive touch of the user may increase the power consumption of the electronic device and cause a problem of shortening the battery usage time. On the other hand, when the user's touch is input when the application processor operates in the sleep mode, the application processor must switch the operation mode beforehand, so it may be difficult to provide the haptic feedback immediately after the touch input.

Various embodiments of the present document allow the touch controller and the haptic controller to communicate directly with each other or in one configuration so that the user can be provided with immediate haptic feedback without intervention of the application processor.

An electronic device according to an embodiment of the present invention includes a touch sensor for sensing a touch, an actuator, a touch controller for generating a touch event based on a touch signal received from the touch sensor, and a haptic controller Wherein the haptic controller receives a touch event generated from the touch controller by direct communication with the touch controller, and drives the actuator in response to reception of the touch event.

According to an embodiment of the present invention, there is provided a method of detecting a touch, including: detecting a touch; generating a touch event based on a touch signal received from the touch sensor; Receiving the touch event generated from the touch controller by communication, and driving the actuator in response to receiving the touch event.

According to the embodiments disclosed herein, an electronic device can provide haptic feedback to a user by direct communication between a touch controller and a haptic controller, thereby reducing the number of times the application processor is driven and providing a fast response speed. The electronic device can provide immediate haptic feedback in response to a user's touch even when the application processor is in the sleep mode.

In addition, various effects can be provided that are directly or indirectly understood through this document.

According to one embodiment, when the touch sensor 332a senses the user's touch, the touch sensor 332a can transmit the touch signal to the touch controller 341a. In one embodiment, the touch of the user may be formed by forming a specific pattern, and the touch signal may be generated continuously based on the specific pattern. The touch controller 341a can obtain the specific pattern by successively calculating coordinate data (X, Y) of the position where the touch is made from the continuous touch signal.

For example, when the user's touch is detected outside the designated area, the touch controller 341a does not recognize the touch signal and may not determine whether or not the touch signal corresponds to the designated pattern. As another example, if the touch controller 341a detects the user's touch in the designated area, it can determine whether the sensed touch corresponds to the designated touch pattern.

According to one embodiment, the designated area may correspond to an area where a specific operation is performed when a touch is performed. For example, the particular action may correspond to an action corresponding to pressing a physical home button.
